FOR IMMEDIATE RELEASE


             CD RADIO EXPANDS TO 100 CHANNELS WITH FOURTH SATELLITE


New York, N.Y. - May 29, 1998 - CD Radio Inc. (Nasdaq: CDRD) announced today
that it has exercised its option to purchase a fourth satellite from Loral Space
& Communications Ltd., doubling CD Radio's planned broadcast capacity to 100
channels in its nationwide satellite-to-car radio broadcasting system scheduled
for launch beginning next year.

"In terms of incremental value delivered to consumers, the step-up from 50
channels to 100 channels is analogous to the difference between a regular
bookstore and a Barnes and Noble superstore," said David Margolese, CD Radio's
chairman and chief executive. "The expanded system will be used to deliver more
of what people want -- more music, more choice. Additionally, it will also be
used to address the Hispanic and sports markets in a significant way, and to
generate additional advertising revenues on our non-music channels."

Under terms of the agreement, Loral replaces Arianespace as CD Radio's launch
service provider, delivering three Loral FS-1300 satellites in-orbit on a
turnkey basis along with one ground spare. Launches are scheduled for November
1999, December 1999, and January 2000. CD Radio's incremental cost of the
expanded system is approximately $290 million, of which Loral has provided
assistance in arranging $145 million of financing primarily through Bank of
America.

Last year, CD Radio was granted one of two FCC national satellite radio
broadcast licenses. The company is building a satellite-to-car 100 channel radio
system for the broadcast of music and other programming to motorists throughout
the United States. The majority of CD Radio's planned programming formats are
generally unavailable on conventional radio stations in any single market.
Furthermore, unlike conventional stations, which have an average range of
approximately 30 miles before reception fades, CD Radio's signal is designed to
cover the continental United States coast to coast. Music channels will be
commercial-free, unlike conventional stations which interrupt their broadcasts
with up to 18 minutes of commercials during every hour of music programming.

Any statements that express, or involve discussions as to, expectations,
beliefs, plans, objectives, assumptions or future events or performance (often,
but not always, through the use of words or phrases such as 'will likely
result,' 'are expected to,' 'will continue,' 'is anticipated,' 'estimated,'
'intends,' 'plans,' 'projection,' and 'outlook') are not historical facts and
may be forward-looking and, accordingly, such statements involve estimates,
assumptions and uncertainties which could cause actual results to differ
materially from those expressed in the forward-looking statements. Accordingly,
any such statements are qualified in their entirety by reference to, and are
accompanied by, the factors discussed in CD Radio's Annual Report on Form 10-K
for the year ended December 31, 1997. Among the key factors that have a direct
bearing on CD Radio's results of operations are the potential risk of delay in
implementing CD Radio's business plan; increased costs of construction and
launch of necessary satellites; dependence on satellite construction and launch
contractors; risk of launch failure; unproven market and unproven applications
of existing technology; and CD Radio's need for additional substantial
financing.
